MACHINE EOEI OPERATING oN HEEILS,

To all whomiz't mag/concern: i

Be it known'that I, JOHN F. STANDIsE, a

citizen ofthe United States, residing at Winthrop, in the county of Suffolk and State of Massachusetts, haveinvented certain' Improvements in Machines for Operating on-4 Heels, of which thefollowing description, in connectionwith the accompanying draw`' ings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates'to l machin-esy for `operating o'nthe heels of boots and shoes and is herein shown .as embodied in afma; chine for attaching Wooden heels although nany of its features could be embodied with good advantage in machines for attaching heels of other types or in machines for per` forming other operations on heels.

In attaching wooden heels itis the prac- 'tice to drive the attaching nails Dfrom Within the shoe While the heel is supported upon the heel seat portion of the outsole. It is im'- v o d the heel vfirmly in the proper portantto h position duringthe driving operation although the pitch and shape 'of the heel ren- -vders this extremely diflioult. One featurefof the present invention relates' to improvements in the heel holding elements of the machine As herein shown a head is provided for supporting the heel against the v thrust of the drivers and separate members are arrangedto engage the surfaces of the heel .Y which face'tovvard-the head i. e., the tread f a'ce and the rear sloping surface of the heel,

- said members being movable to adjust themselves automatically to the contour 'of heels ofvarious z'shapes and' to maintain their adjusted positions rigidly duringthe operation of the drivers. Heretofore separate heel engaging members have been provided but-it has been necessary forthevoperator to adjust eachof the members'by hand 1n accordance With the size and shape of the particular heel "being operated upon and, as there is likely to be considerable variation-in these respects, the operation ofthe machine' has been necessarily slow.

. equalized.l i Anotherv feature" ofthe invention more especially to the driving olifpricking f mechanism and consists in 'means' for adi .justably retaining and guidingthe of,

These andother features of the invention will be best understood andappreOiated-mm the following description' of a preferredlembodiment thereof selected forv purposes of illustration and shown in the accompanying drawings, in i Which,-

The embodiment of the invention herein illustrated is shown as applied to a -heel attaching machine of the type disclosed in United States Patent No. 1,081,917 granted December 16, 1913 on ari-application of E. A. Tripp. Those parts of the machine not herein illustrated may correspond substantially to the similar parts disclosed in said patent.

r1`he machine frame 2 is provided with a stationary support 3 for the jack i in which the drivers are mounted. The jack is shaped to support a slice in an inverted position beneath the movable head 6 which is. mounted to slide vertically in suitablev -ways formed in the frame 2. The head -6-is arranged to be moved downwardly to support the heel against the thrust of the drivers and `for this purpose is provided with a rell'er which runs upon the periphery .of a spiral cam 8 journaled in stationary bearings on the machine frame 2 and geared t'o'a rack which is operated by a vertically extending rod 10. The rod 10, as in the patent above referred to, may be depressed b 'the operator through a treadle, not s own,` at the base of the frame.

The function of the head 6 is to press the loose heel upon the heel seat of a shoe positioned on the jack and to maintain the heel lin position without slipping during the driving operation. To this end the head is provided at its lower side with horizontal guideways in which is mounted a carriage 12 for the heel holding members. The carriage 12 at its forward end is .provided with a rod 14 upon which is threaded an adjusting wheel 16. The Vwheel 16 has. a grooved hub which receives a circular rib projecting from the head 6 by which it is held in position longitudinally while per mitting the rotaryA movement to s hift the carriage 19o-back 'and forth longitudinally of the shoe. Y

f Thecarriage 12 is provided with two parelo allel vertical guideways' in one of whichv is slidingly mounted the shank piece 18 of the member "which engages the tread face of the heel. The. tread engaging member itself' comprises a block 20 curved at its upper edge and fitted for adjusting movement in a curved guideway in the shank piece 18. The upper edge of the block 20 is provided with gear teeth which mesh with the teeth of 'a worm 24 mounted in the shank piece 18.

The angular position of the tread engaging face of the block 20 may be adjusted to suit the requirements of the work by turning the worm 2e. v

1n the rearmost uideway in the carriage y piece 26 and is held in position by a locking nut 32. When the latter is loosened the angular position of the forked member may be varied and its adjusted position maintained by tightening the nut 32. At its lower end the forked member 28 is provided with a facing of yielding material, such as leather, to prevent scratching of the polished surface of the heel.

, It will'be apparent that the shape and relation of the tread face and the rear curved surface of the heel will vary considerably in changing from one size of shoe to another or on account of differences in height or style of the heels. The two heels engaging members above discussed are arranged to adjust themselves automatically to the heel being operated upon regardless of its shape or style. To this end the proximate faces of the shank pieces 18 and 26 are provided 'with rack 'teeth which mesh upon opposite sides of a pinion 40 journaled in the carriage 12. With this construction it will be seen that the movement of one heel engaging member is transmitted tothe other as an equal movement in the opposite direction. The shank piece 18 is bored out to receive a spring 38 which bears at its upper end upon a. cover plate 34 bolted to the carriage and tends normally to move the block 2O downwardly. An adjusting screw 36 is set in the cover plate 34 in position to engage the upper end of the shank piece 26 and so determine the initial position of both heel engaging members. rIhe spring 38,'it will be.understood, moves the tread engaging member downwardlyl and the forked memtion of these two members is so determined that the tread face of the heel shall engage the block 20 before the forked member` 28 is engaged rby the rear surface of the heel.

`When the head 6 is depressed therefore the. V'block 20 is moved upwardly in the head 12 andthe forked member moved downwardly until it enga-ges the heel, the relativemovement continuing until the pressure of the twol members upon the heel is evenly balanced.

The jack 4 has secured to its upper end a pair of spacedplates-O and 52 shaped toA through which extend driver guiding tubes 54 for Athe drivers 48. -The drivers 48 are -carried by a -reciprocatory plunger 42 which has secured to its upper end a plate 44 spaced from the body of thefplunger by dis.

tance pieces 46. The plate 44' is provided With a slot extending from front' to rear, for

receiving the rearmost driver, and with di-v -vergent slots 45 for receivingthe side driv- 'ers. As hereln 'shown five drivers are provided, this 4being the number usually employed, although it would be within'the scope of the invention to employ any desired number of drivers. Each of the drivers 48 has secured to its lower end tend up through the slots in the plate. 44

Ali() a block 49 having square sides which expermitting the drivers to be adjusted on the flat driver engaging face of the plunger in `the `direction of the slots. The. upper ends of the drivers are beveled slightly as shown in Fig..2' to cause theattaching nails to enter the heel in a convergent manner.

The drivers are loose on the plunger 42.

and are maintained in the desired'position 4by the guiding tubes 54'whichare adjustably but rigidly held in place during the operation of the machine. Each of the side driver guiding tubes 54 is rigidly set in a- 4gage block 56 which is received between the two spaced plates 50 and 52 of the jack top. The'gage blocks are so shaped as to permit .the guiding tubes54 to slide transversely but 'tagon shown in dash lines in Fig. 7.

' The outer edges of the gage blocks 56 are intended to contact with the sides of the shoe being operated upon and to locate the ,same symmetrically with respect to the drivers and the attaching nails driven by them. These blocks also act to limit the distance between the attaching nails and the edge of the work `and areso proportioned as to' bring the attaching nails as close to the edge of the heel as is practical without danger of the nails splitting the heel or driving out through its side surfaces. When the guiding tubes 54 are adjusted for the largest shoe the drivers occupy the. positions indicated in Fig. 7 by the large pentagon shown in dotted lines while the outline of the gage blocks corresponding to this adjusted position is also indicated.

,Ordinarily it is necessary only to adjust the side drivers as the distance from the rear of the heel to the rearmost attaching nail requires 'but slight adjustment in heels of various sizes. As herein shown the guiding tube forthe rear driver is threaded at its upper end to receive a set nut 62 by which the tube may be clamped rigidly to the plate 52. The slot 53, however, permits adjustment of this tube and the corresponding driver longitudinally of the shoe. The side drivers are simultaneously adjusted by is mounted beneath the iiXed plate 50 and provided with an adjusting screw by' At their upper ends the guiding tubes 54 are provided with conical heads which en-v gage directly with the heelvseat portion of the insole of the shoe. As the drivers are arranged to move to the end of the guiding tubes this construction insures that the attaching nails shall be driven with their heads flush with the insole regardless of the transverse curvature of the sole. This results from the fact that the sole is supported on a'number of isolated points of small dimension and does not have to be the movement of a slotted frame 58 which Y These are so shaped as to maintain l lall tunes 1n a sym-v' conformed to a plate which may, not coiny cide with its curvature.

In placing -a shoe upon the jack` it sometimes happens that the operator'will bear down upon the forward portion thereof and break a shank downwardly While the heel seat portion is clamped between the heel and the jack top. To eliminate such occur- :rencel there is provided a supporting member' 68 having a flat end arranged to bear upon the inside of the shoe shank as shown, in Fig. 2; For purposes of adjustment a vertical slot 66 is provided in a rib formed* on the forward side of the jack post and the support 68 is clamped in adjusted position by a clamping bolt 69.

In operating the machine herein described the shoe to be heeled is placed upon the .jack 4 vas shown in Figs. l and 2 and the adjusting screw ou turned to bring the gage blocks 56 into engagement vvith'the inside ot the shoe, this adjustment properly locating the drivers for the shoe to be operated upon. The head 6 is then depressed through the treadle rod l0 until the engaging members 20 and 28 have been brought into even' bearing upon the tread and rear surface ot' the heel. Vhile the head is maintained in this position the machine is started and the drivers elevated forcing the attaching nails through the sole and into the heel. The operation may then be repeated and no turther adjustments are necessary until it is desired to ope-rate upon shoes of a different size. j
